What is your favourite Nintendo franchise?

Other than maybe Sega I can't think of another gaming company that creates as many diverse games as Nintendo. Although some of their biggest franchises are platformers they have actually branched out in to a lot of different genres, from strategy to RPGs and even racing games. So, which is your favourite Nintendo franchise? My pick is The Legend of Zelda because, outside from being a fantastic franchise of games, it was the Zelda games that really got me to take gaming seriously, and they are the reason I am the gamer I am today.

Pokemon, Kirby, Mario and the DKC games. Never really got into Metroid and the Zelda games were hit or miss with me but I really liked Ocarina. Should've played more of Twilight and Skyward Sword was good of what I played, need to play that again.
